Your Queries:
Q1. In the meter bridge experiment,balance point was observed at J with AJ=I.
i) The values of R and X were doubled and then interchanged.What would be the new position of balance point?
ii) If the galvanomater and battery are interchanged at the balance position,how will the balance point get-affected?
Q2. The figure shows experimental set up of a meter bridge. When the two unknown resistances X and Y are inserted, the null point D is obtained 40 cm from the end A. When a resistance of 10Ω is connected in series with X, the null point shifts by 10 cm. Find the position of the null point when the 10Ω resistance is instead connected in series with resistance 'Y'. Determine the value of the resistance X and Y.
Q3. In a meter bridge, the balance point is found at a distance l1 with resistances R and S as shown in the figure. An unknown resistance X is now connected in parallel to the resistance S and the balance point is found at a distance l2. Obtain a formula for X in terms of l1, l2 and S.
